      There are no clear steps to reproduce, but the general idea was

      • to setup the architecture as described in the doc linked in description
      • Create several kie-server instances using s2i build. Using s2i template parameters we made the kie-servers to connect to smart router
      • Go to Execution servers and try to perform some admin operations with the containers (start / stop / remove).

    Description

      In our "smart router + monitoring workbench" test day setup described here we saw several NullPointerExceptions in the server console of smart router after some basic manipulations in ServerManagement ui:

      May 15, 2018 12:52:05 PM org.kie.server.router.handlers.AdminHttpHandler lambda$handleRequest$0
ERROR: Error while performing admin operation
java.lang.NullPointerException

      The NPE is apparently coming from here.

          is related to

          Bug - A problem that impairs or prevents the functions of the product. JBPM-7280 NPE when removing container in smart router

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
